The MCLR pin can trigger an external Reset of the
device by holding the pin low. These devices have a
noise filter in the MCLR Reset path that detects and
ignores small pulses.
The MCLR pin is not driven low by any internal Resets,
including the Watchdog Timer.
In PIC18F2331/2431/4331/4431 devices, the MCLR
input can be disabled with the MCLRE Configuration
bit. When MCLR is disabled, the pin becomes a digital
input. For more information, see
“PORTE, TRISE and LATE

time, see
When the device starts normal operation (i.e., exits the
Reset condition), device operating parameters (such
as voltage, frequency and temperature) must be met to
ensure operation. If these conditions are not met, the
device must be held in Reset until the operating
conditions are met.
Power-on Reset events are captured by the POR bit
(RCON<1>). The state of the bit is set to ‘0’ whenever
a POR occurs and does not change for any other Reset
event. POR is not reset to ‘1’ by any hardware event.
To capture multiple events, the user manually resets
the bit to ‘1’ in software following any Power-on Reset.
